Yes. That pic is definitely your air cond. Not just brake pads but also the disc rotors coul be glazed over (burnt) I usually do both at once. If the rotors are still thick enough within specs they can machine them or your up for newies. Compare the prices. Not usually that dear. About $50 a pair to machine. It does sound like the problem but, especially with a couple of ton of pommy engineering to try to stop.
